How to Open and Export CSV Files

Comma-separated values (CSV) files are widely used for storing tabular data. They are simple text files where each line represents a data record. In this guide, we’ll demonstrate how to open CSV files with Excel’s built-in features—whether direct opening or connecting via Power Query. Moreover, we’ll explore exporting data to CSV format, all from within Excel. By the end of this article, whether you’re adept or just beginning, you’ll possess the know-how to effectively manage CSV files, an essential skill in today’s data-driven environment.

Import a text file by opening it in Excel

Opening a CSV file in Excel is straightforward and requires only a couple of steps. First, launch Excel and click on “File” in the menu. Next, select “Open” and navigate to the required CSV file location. Ensure the file format dropdown in the dialog is set to “All Files” or “Text Files” to display CSV files. Selecting the CSV file will take you through Excel’s Text Import Wizard if necessary, customizing how text is split into columns and rows based on delimiters.

When importing, the Text Import Wizard provides options to define delimiters like commas or semicolons, the text qualifier (often a quotation mark), and data type for any columns. This meticulous approach ensures data is correctly formatted and interpreted. Importantly, if the CSV has embedded commas within fields, use text qualifiers to avoid misinterpretation.

Import a text file by connecting to it

Another method of importing CSV files into Excel is by establishing a connection. This technique is beneficial when dealing with large datasets or data from an active database. To begin, open Excel and navigate to the “Data” tab. Here, opt for “Get External Data,” followed by “From Text.” This task activates the Text Import Wizard, which guides you through determining delimiters and column data formats, akin to directly opening a CSV file.

The key advantage of establishing a connection is the ability to refresh data with ease. Therefore, any updates made to the original CSV file can reflect dynamically in your Excel sheet when refreshed. This functionality is ideal for ongoing projects requiring up-to-the-minute data insights.

Import a text file by connecting to it (Power Query)

Power Query offers robust tools for importing and transforming data, especially helpful when managing CSV files. To activate this, open Excel, access the “Data” tab, and select “Get Data.” Choose “From File” and then “From Text/CSV.” Power Query identifies data structure automatically and proposes a load preview.

The strength of Power Query lies in its flexibility to transform data using an intuitive editor. Applying various filters and transformations can refine the data to meet specific analysis needs before loading it into Excel. Subsequently, any modifications to the CSV file can be refreshed, leveraging Power Query’s querying capabilities for real-time accurate data.

Export data to a text file by saving it

Exporting Excel data to a CSV format involves a seamless process, perfect for sharing or transitioning data between applications. Once your data sheet is ready, proceed to “File,” then “Save As.” Choose a destination for the file and from the “Save as type” dropdown, select “CSV (Comma delimited) (*.csv).” This operation translates complex Excel data arrays to the simplified CSV format, maintaining structure across any spreadsheet program.

Bear in mind, the CSV format doesn’t support multiple sheets or advanced formatting present in Excel. Therefore, ensure essential information is consolidated on a single sheet before exporting. CSV files only retain simple data representations and will disregard Excel-specific settings such as formulas or cell formats.
